Application led November To @ZJ 'iu/'iam if 'may concern Be it known that-I, Tl/innrsii H. linnonn, ti/.en ot the United States7 and `a resident ot the city ot Portland, county oi Multnoinali and :i .te ot' Gregori, have invented rain new and useful improvement in age' Fasteners, otl which the Jiiollovving` peciication. -lie object of my invention is to rprovide an inexpensive device for fastening the lapping end of a surgical bandage securely in place; and which furthermore is more easily applied and is more ei-.cientrthan either a sat'ety pin or tape. i 3

I attain my object in a fastener made Vof resilient materialyand adaptedfnormally to assume an arcuate curve and to be flattened Y by pressure.` The opposite ends oic the body are provided with inwardly extendingflat fabric engaging projections. which. in the normal torni of the body, are positioned to lie in the plane ot the4 chord otsaid arcuate curve.. Butvvvhen my fastener is to be applied to a bandage and itsbody is flattened by pressure, `said projections ywill be caused to assume an anoular position with Vrespect Vto said plane and extend below tlielatten*l `Jthereby' being4 arranged so as to be capable i ot penetrating.r thebandag'e material. Then when the pressure is removed the rellen ac tion otthe body will canse said projections to engage Withf'said fabric and thns'secure Fig. el; the dottedlines of Fifi. 2 showin; the bandage `fastener heme pressed into the position illustrated by Fig. 5, 'in which position the pin points provided at the endsot'Y the 'Fastener may penetrate thebandage material so as to secure the laps in place;

and i Figs. Li and 5. as already mentioned, illustrate the operation of my fastener,

VMy fastener comprises body a made eta resilient7 i'lat piece 'ot'nietah and which may be shaped as shown, ielyy e middle part Aotgthe body beine- `reduceo jso as to givey lgreater resiliency andtienibility to this por-Vfv tioin; VWhile atl the` same time retaining lore i or less rigidity at the ends of the fastener. rlheends ofthe fastener e providedL with a plnralityof fabric eng; 'Y projection'sj. and Zi, curved inwardly', and

The tabi'ic'engaging projections l) and b are preferably made intlie torni of serra-k tions therebyV tending' to limit the penetration ot these project-ions into the bandage material and thus facilitating the removal ot my .fast-ener. In other Wordsythe bandage material will tend to lpull the serrations when my fastener is depressed so toA be Hat.y as done when the fastener is to be removed. .At the same time the v.enoagenient ot' said projections ivithlthe bandage matei riall will be ample to securely fasten theV bandage in plac In order to facilitate the bandage, one endv of my fastener maybe.V provided with a linger piece or-lipc. Such`4 construction, however. is optional.Y

ift will be apparent that my bandage may v i 105,` the removal from be inexpensively stamped out of asheet of metal, and readily formed to the shape desii-ed.

I claim:

l. A bandage fastener comprising,l a body made of resilient material, reduced in width at its middle to increase its flexibility and adapted, normally, to assume an arcuate curve and to be flattenedV by pressure; the opposite ends ofthe body being'provided with flat, inwardly extending fabric engaging projections which, in the normal form ofthe body, are positioned tollie in the piane of a chord; of said arcuate curve;

/whereby when the body is lliattened by Jressure said oro'ections will be )ositioned i 1 i c,

at an angie to, and project below said plane for engagement with the bandage material,

and whensaid pressure is removedthe reflex action of the body will cause said progections` to engage with said fabric, at the "Same tim@ mOYng the extremities of said PXQJGCUODS lWy flOiIithe inner-face of the u lie in the plane of a chord of said arcuate curve; whereby when the body is flattened by pressure said serrations will be positioned at an angle. to, and project below said plane for engagement with the bandagematerial, and when said pressure is removed the retlex'action of the body will cause said provjections to engage with said fabric, atV the same time movingy the extremities of said serrationsaway from the inner face of the bandage, and renderingr it incapable of penetratinpy the latter. v v
